Division of two floating point numbers using pointer in C++
In this tutorial, we will discuss the concept of Division of two floating point numbers using pointer in C++
In this topic, we are going to learn how to divide two floating point numbers using pointer in C++ programming language
What is division
The division is a method of splitting a group of things into equal parts. The division is an arithmetic operation inverse of multiplication
It is one of the four basic operation of arithmetic calculation others being addition,subtraction,multiplication
The division of two natural numbers means it is the operation of calculating the number of times one number is contained within one another
C++ exercise to Divide two floating point numbers
Program to division of two floating point numbers using pointer
Program 1
In this program, the user initialize two floating point numbers using two variables and then the program calculates the division of the given numbers using the pointer in C++ programming language
#include <iostream>
#include <conio.h>
using namespace std;
int main()
{
float num1=30.0,num2=2.2;
//Declare and initialize float variables
float *ptr1,*ptr2;
//Declare float pointer variables
ptr1=&num1;
//Assign the address of num1 to ptr1
ptr2=&num2;
//Assign the address of num2 to ptr2
float div=(float)*ptr1/ *ptr2;
//float division
cout<<"Division is: "<<div;
//display result on the screen
getch();
return 0;
}
When the above code is executed, it produces the following result
Division is: 13.6364
Program to division of two floating point numbers using pointer – Entered by user
Program 2
The program allows the user to enter two floating point numbers and then it calculates the division of the given numbers using the pointer in C++ programming language
#include <iostream>
#include <conio.h>
using namespace std;
int main()
{
double num1,num2,div;
//Declara double variables
double *ptr1,*ptr2;
//declara double pointers
cout<<"Please enter the two float numbers\n";
//Ask input from the user
cin>>num1>>num2;
//Reading the input from the user
ptr1=&num1;
//Assign the address of num1 to ptr1
ptr2=&num2;
//Assign the address of num2 to ptr2
div=(double)*ptr1/ *ptr2;
//Division of two floats
cout<<"Division is: "<<div;
//Display result on the screen
getch();
return 0;
}
When the above code is executed, it produces the following result
Please enter the two float numbers 45.00 12.00 Division is: 3.75
